Comment #2 on issue 2571 by [email protected]: tuplet bracket starts to late
when the expression starts with a spacer
http://code.google.com/p/lilypond/issues/detail?id=2571
I don't know if you accept the example in the origin of this issue as
making sense
(http://old.nabble.com/tuplet-bracket-starts-too-late-after-shorter-rest-ts33918372.html)
but I can imagine a polyphonic situation where everything is very tight and
you wouldn't know how and where to squeeze an additional rest, e.g.:
\new Staff <<
\relative { <c'g>1 <c g>1 }
\\
\relative { c2 c c2 c }
\\
\relative { \voiceFour
\times 2/3 { r4 e e } \times 2/3 { e4 e e }
\times 2/3 { s4 e e } \times 2/3 { e4 e e }
}
